Proposing a new LHC search for light compressed stop squarks

Paper in proceeding, 2015

The LHC searches for light compressed stop squarks have resulted in considerable bounds in the case where the stop decays to a neutralino and a charm quark. However, in the case where the stop decays to a neutralino, a bottom quark and two fermions via an off-shell W-boson, there is currently an unconstrained region in the stop-neutralino mass plane, still allowing for stop masses around 100 GeV. In this note we will propose a new monojet-like search for light stops, optimized for the four-body decay mode, in which at least one b-tagged jet is required. We show that, already by using the existing 8 TeV LHC data set, such a search would cover the entire unconstrained region. This note is based on ref.
